The Impact of Investment Opportunities and Free Cash Flow on Financial Liberalization: A Cross-Firm Analysis of Emerging Economies

Capital account liberalization leads to higher equity prices, lower capital costs, private investment booms, greater capital flows, and higher economic growth.
As suggested by Martell & Stulz (2003), stock market liberalization increases the pool of investors who are able to invest in firms.
However, the extent to which a country actually benefits from stock market liberalization is largely dependent on the extent to which firms can take advantage of it.
It may in fact have a negative economic impact on firms if the costs of liberalization outweigh the benefits.
A firm-level analysis thus provides us with important information that might enable us to assess the impact of capital account liberalization and the channels through which such liberalization affects firms.
This study investigates the role of investment opportunities and free cash flow in explaining the value-enhancing potential of stock market liberalization at firm level.
As argued by Henry (2000b) & Bekaert et al. (2001), stock market liberalization expands a firm’s investment opportunity set and stimulates its investment as a direct result of the falling cost of equity capital following liberalization.
The value-enhancing potential of investment depends on the availability, or lack, of investment opportunities (Lang et al., 1989 & 1991; Doukas, 1995; Brailsford & Yeoh, 2004).
Specifically, for firms with good investment opportunities, corporate investment is generally regarded as worthwhile, whereas such investment by firms with poor opportunities is not.
This suggests that stock market liberalization creates greater value for firms with high growth opportunities, and less value for firms with low investment opportunities.
Martell & Stulz (2003) also argue that stock market liberalization is more beneficial to high-growth firms because the local market may not provide sufficient funding to meet their capital needs.
While stock market liberalization results in a reduction in the cost of equity capital, it may also create incentives for overinvestment.
Berkovitch & Kim (1990) suggest that the lower cost of capital will create incentives for firms to engage in excessive investment, which may take the form of accepting negative NPV projects.
Such potential for overinvestment is expected to be more serious for firms characterized by high free cash flow.
The free cash flow theory of Jensen (1986) argues that potential agency conflicts arise when managers have control of cash flows in excess of those necessary for profitable investment.
Such agency costs come as a result of managers’ using their excess cash flow to overinvest in the firm, so that shareholder wealth is not maximized.
Thus, if Jensen’s theory holds, we expect that the value of stock market liberalization will have an inverse relationship with the existing level of free cash flow within a firm because the potential agency costs are higher for firms with high cash flow.
There is an alternative hypothesis which predicts that stock market liberalization may create greater value for firms with high cash flow than for those with low cash flow.
Stulz (1999) and Martel & Stulz (2003) note that stock market liberalization reduces the cost of capital, not only by sharing risk, but also by improving corporate governance.
The introduction of foreign investors increases monitoring intensity, thereby reducing the agency costs of free cash flow.
This implies that following liberalization, firms that are prone to agency problems, such as those with high free cash flow, are more likely to experience greater increases in equity value.
ADRs and country funds represent two additional forms of stock market liberalization that allow stocks to be traded in the developed markets and that have the potential of more effectively reducing barriers to liquidity and information.
Most of the prior studies have focused on the effects of the first liberalization events, irrespective of the various forms of liberalization.
In this study, we examine all three main types of stock market liberalization.
The data on firms in the remaining nine countries are obtained from Datastream and Worldscope.
We use daily stock returns to examine the announcement effect of stock market liberalization.
We also use financial statement data to calculate proxies for the growth opportunities, free cash flow, and control variables.
We do not calculate abnormal stock returns through the use of historical betas.
As an alternative, we use measures of firm size, leverage, dividend yield, industry dummies, and country dummies in the regressions to control for those factors that could affect expected returns.
Tobin’s q, defined as the ratio of a firm’s market value to the replacement costs of its assets, is perhaps the most commonly used measure of growth opportunities (Denis, 1994).
We estimate q as the ratio of the market value of the firm’s assets to the book value of the firm’s assets, where the market value of assets equals the book value of assets minus the book value of common equity plus the market value of common equity.
The q variable is measured at the end of the fiscal year preceding the announcement of stock market liberalization.
High-q firms are regarded as firms with good investment opportunities while low-q firms are regarded as firms with poor investment opportunities.
Unfortunately, as pointed out by Lang et al. (1991), the literature provides little or no guidance on the measures for free cash flow as defined by Jensen (1986).
We thus adopt the most widely used definition of free cash flow, which is operating income before depreciation minus interest expenses, taxes, preferred dividends, and common dividends for the fiscal year preceding the announcement (e.g., Lehn & Poulsen, 1989; Lang et al., 1991; Lie, 2000).
Free cash flow is normalized by the book value of total assets.
Chui & Wei (1998) find a strong size effect in emerging markets, where stock returns are negatively related to firm size.
Laeven (2003) also points out that the effects of financial liberalization in emerging countries differ between small and large firms.
The debt ratio reflects the firm’s leverage risk and is related to the stock returns.
Moreover, debt can be used to monitor managerial inefficiency and mitigate the agency problem (Hart & Moore, 1990, and Stulz, 1990).
Thus, the debt ratio may affect a firm’s performance.
Following Henry (2000a), we use an eight-month period (–7, 0) to measure the price reaction to the announcement of stock market liberalization, where month 0 is defined as the month of liberalization.
We examine the announcement-period returns for all three types of stock market liberalization.
We obtain estimates of abnormal stock returns on the basis of the market model, with the abnormal return being calculated as the difference between the actual return and an expected return generated by the market model.
We estimate the parameters of the market model using data over the period from month –20 to month –9 before the month of stock market liberalization.
The cumulative abnormal returns are calculated by summing up the daily abnormal returns over each event window.
We compute the buy-and-hold returns by compounding the daily returns over each event window.
Three alternative free cash flow proxies (Lang et al., 1991):
(1) net income plus depreciation plus adjustment for other elements in income that do not affect working capital, divided by the book value of total assets;
(2) operating income before depreciation minus interest expense, taxes, preferred dividends, and common dividends, divided by the book value of equity;
(3) the same definition of free cash flow as in (2), divided by the sum of the book value of equity and the book value of long-term debt.
We examine the valuation effects as measured by Tobin’s q rather than announcement-period returns (as in Morck et al., 1988, and Carter et al., 2006).
We use data on our sample firms over the period 1980-1998 to examine changes in Tobin’s q surrounding all three types of stock market liberalization, with the results.
The dependent variable in Models 1 and 2 is the growth rate of Tobin’s q, while the dependent variable in Models 3 and 4 is the change in Tobin’s q.
We also control for the potential effects of country- and industry-specific differences by including industry and country dummies in the regressions.
However, unlike stock market liberalization, banking sector liberalization occurs gradually over a longer period of time.
The prior literature provides examinations of 6 types of banking liberalization, including the liberalization of interest rates, the removal of entry barriers, the lowering of reserve requirements, the removal of credit controls, the privatization of state-owned banks, and the introduction of prudential regulation (Laeven, 2003; Abiad & Mody, 2005).
We investigate the stock valuation impact of banking liberalization at firm level for the emerging markets in our sample.
Such data on financial liberalization for the emerging markets is provided by Kaminsky & Schmukler (2003) and Bekaert and Harvey (2004).
We thus obtain the banking liberalization dates from their studies.
Our evidence suggests that at firm level, the average (median) increase in stock returns during periods of banking liberalization is approximately 2.4% (1.2%) per month.
Therefore, consistent with our findings on stock market liberalization, banking liberalization announcements are associated with significantly positive stock valuation effects.
Our results are consistent with the investment opportunities hypothesis and continue to hold after controlling for other factors which could affect market responses to such announcements.
Our findings suggest that the availability, or lack, of investment opportunities is an important consideration in assessing the value of financial liberalization.
We show that high-cash-flow firms have lower announcement-period returns than low-cash-flow firms.
Our findings are consistent with the expectation under the free cash flow hypothesis that the value of financial liberalization has an inverse relationship with firms’ existing free cash flow levels.
Our results suggest that the free cash flow hypothesis dominates the corporate governance hypothesis in terms of the net effect of financial liberalization on the firms’ stock returns.
